This paper will describe the practice of scientists who position their own practice as the one distinct from the "Naturalistic" Science, which presupposes the distinction between Human and the Reality. In this paper, the characteristics of solid earth physicists' practice, who consider physics as representational practice and regard their own practice as "Non-Naturalistic" are described upon the key concept, "Fusion." Their practice is characterized by seemingly strange ideas, such as "distrust of observed data" and "a priori data." In the science of "Fusion," human assumptions and evaluations are treated as a kind of "data." Observation data are "imported" into models by "Inversion" or "Data Assimilation," instead of simple "comparison" between models and data. The outcomes of the science are no longer "objective representations" based on the dualism of the world and human, but rather hybrid images of observation data and human model evaluation mixed in a unique way.
